Which do you think is rarer in natural populations, underdominance or overdominance?  Explain your reasoning within the context of how selection operates in populations.

Which of the following graphs best illustration the relation ship between population size (x) and inbreeding (y)?

Consider two species, 1 and 2, that experience different mutation rates with m1 < m2, and have population sizes of N1 < N2.  Which species would you expect to have a lower frequency of heterozygotes at a neutral locus?  Explain your reasoning.

With enough time and in the absence of other evolutionary mechanisms, genetic drift will __________ genetic variation in the population.

Heterozygote superiority can also be stated as the term __________.

The concept of __________ is most likely to maintain genetic variation in populations by favoring rare alleles.

When deleterious recessive alleles are present in a population at a low frequency, the rate at which selection will remove them from the population is __________ (low/high).

A hypothetical population has two alleles for a gene: L and R. In a random sample of individuals, 97 are homozygous for L, 127 are homozygous for R, and 112 are heterozygous. What is the frequency of L?

When highly deleterious mutations are being rapidly introduced into a population, the equilibrium frequency will be __________ (low/high).

The concept of __________ is most likely to remove deleterious alleles in populations.
